Read the data sheets for the devices in use, front to back.Hello,
I use MK60DN512VLL10.
I have to use at least 65 ADC data, probably I will use ADS1158 16-Channel, 16-Bit Analog-to-Digital Converter.
I want to know that How many SPIs can hardware connect to the processor's SPI port?
I've never - in untold years - NOT found such crucial information in the data sheets. As someone has already pointed out, there are DYNAMIC aspects to the 'fan-out' on the signal lines - signal frequency for one. However, IF, on absorbing the data you see no immediate red flags, then put it together and try it. Any problems can be addressed with test equipment and analysis only if there ARE problems - I'd rather that than spend days speculating and asking around with nothing to get my hands on.
